AJ820C Use Case
Enterprise Virtualization Consolidation with AJ820C-HP SAN Switch
In a global financial services data center running VMware vSphere on HP BladeSystem servers, the AJ820C-HP B-series SAN Switch delivers 16 Gb Fibre Channel connectivity across 8 or 12 ports to consolidate storage traffic from 200+ virtual machines. By reducing network hops and leveraging its non-blocking architecture, IT teams achieve 40% lower latency, 2× higher VM density and centralized SAN management. The outcome is predictable I/O performance, faster VM provisioning and simplified operations that scale with business growth.
Disaster Recovery and Business Continuity Across Geo-Dispersed Blade Enclosures
A multinational retail chain implements synchronous replication between two BladeSystem data centers using dual AJ820C-HP SAN Switch fabrics. In the event of a site outage, critical order-processing and inventory databases fail over automatically with sub-30-second RTO. The high-availability zoning and Fabric Watch monitoring ensure transparent switchover and eliminate data loss. The benefit is uninterrupted customer service, minimized revenue impact and adherence to strict recovery-time objectives.
High-Performance Computing Acceleration for Data-Intensive Workloads
A genomics research lab deploys an HP BladeSystem cluster for next-generation sequencing analysis. By integrating AJ820C-HP SAN Switches to deliver 16 Gb/s Fibre Channel to high-throughput storage arrays, scientists process terabytes of genomic data with 60% faster read/write operations and sustained IOPS. The streamlined SAN design and port-level monitoring empower rapid scaling of compute nodes. The result is accelerated time-to-insight, increased experimental throughput and lower total cost of ownership.
